We both work, and I honestly don't think we can get by with only one of us working, unless DH finds a better paying job in a state with 11% unemployment (odds are stacked against us). We work opposite shifts. Come January, there will be a baby added to the mix and my maternity leave will be over. Half day kindergarten is our only option in our state. So here is DH's schedule. Please let me know if you think it's doable.

DH comes home at 5 am.
I leave for work at 7:30 am.
DS will wake at either 9 or 10 am and I will have breakfast/lunch ready for them.
School starts at noon. DH has to drop DS off (bundle baby up in winter too)
Pick up at 2:30 pm (again, will have to bundle baby up and go)
I get home at 4:45 pm.
DH leaves for work at 6:30 pm.

Interrupted sleep pattern because of baby/feedings, of course. DH is insisting that he can handle this schedule, which will start in late January. I have my doubts. It seems like a lot to handle, especially with a 6 week old and a 5 year old.

We can try to get the in laws to help, but they want to be paid. SIL offered to drop DS off at school and pick him up if needed, but she works with an unpredictable schedule. My mother is willing to move in, but DH is resistant to that because he wants to raise this baby himself (my parents helped out with our oldest). Also, my sister is due 3 months after me and she's always been the type to heavily rely on my parents for help even though she doesn't work.
